ABSTRACT:
The present invention is related to a device for controlling a cursor to rotate rightwards and leftwards and the method thereof, wherein a X axis sliding bar and a Y axis sliding bar are installed between the cover and base of said mouse, and said X axis sliding bar and said Y axis sliding bar are used as the X axis movable optic grid and the Y axis movable optic grid, respectively, said X axis movable optic grid and said Y axis movable optic grid will rotate with said base within a proper angle. When said cover of said mouse is moved or rotated, said X axis movable optic grid and said Y axis movable optic grid will move or rotate synchronously and match the installation of a light emitted diode, a photo transistor, fixing optic grids and a controlling circuit so that the cursor on the computer display may be controlled with a small active range.
